The popularity of corn silage as a constituent in the rations of Quebec’s dairy cows shows no signs of waning. An analysis of data collected from more than 500 dairy farms confirms that the use of corn silage has a favourable effect on milk yield and composition as well as on the feed profit margin. Further research is needed, however, to determine the overall impact of corn silage on the health and fertility of both soils and herds in addition to the environmental footprint linked to its production.
